It all depends on how hard you run that Caprice. I have a 70 Impala and I almost never go over 3k rpm's with a 400 sbc. I will bring her up to 5k rpms a couple times a week just to make some hot rod noise. I'm still working on stability at high speeds. Everything in the suspension is new and it is a handful to handle over 80 mph. I don't remember them being like this in the old days but hey, I have bikes and a Camaro for going fast.

I'm looking for a big block just for the big block sound. I'm thinking if I score a truck 454 I may try it in stock form for a while. I'm sure the truck 454 will love cruising under 3k rpms with an occasional 5k rpm blast to make some noise. I guess my old Impala is just a fair weather cruiser that doesn't seem to need high horsepower.
